MACHINE FUR CUTTING OFF AND CROZING BARREL STAVES.

SPECIFICATION forming part Of Letters Eatent NO. 679,166, dated July 23,1901. Application filed December 6, 1900. Serial No. 38,921. (No model.)

To coll whom it may concern:

Be it known that I, OLIVER H. P. CORNELL,

a citizen of the United States, residing at Brooklyn, in the county ofKings and State of New York, have invented certain new and usefulImprovements in Machines for Cutting Off and Crozing Barrel-Staves and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to the art of making barrels, has especialreference to crozing the staves, has for its object the manufacture ofstaves from strips of wood properly dressed and of sufficient length tomake several staves in succession, and consists in certain improvementsin construction which will be fully disclosed in the followingspecification and claims.

The prevailing practice of making staves consists in cutting timber of alength to make one stave,then splitting the timber and steaming it, andthen working it into staves, which are then seasoned and subsequentlyjointed and tied in bundles and shipped to the cooper, who squares theends and crozes the staves before making a barrel. By this practice thetimber must be handled a number of times before a completed stave isproduced, which adds materially to the cost of the barrel.

In the accompanying drawings, which form part of this specification,Figure 1 represents an end view of my improved machine, the feedmechanism being omitted to avoid confusion; Fig. 2, a top plan of thesame; Fig. 3, a side view showing the rear of the machine; Fig. 4, aside View of the hinged section of the table detached; Fig; 5, avertical section of the table, the cutting-off tool, and thecrozing-tools, and a side elevation of the shaft which supports thetools; Fig. 6, a side elevation of a section of the cutting-0d tool andof one of the crozing-tools on an enlarged scale; Fig. 7, a like View ofthe clamp for holding the strip to the table while it is being cutoffand the adjacent ends crozed Fig. 8, a side View of a strip of wood withlengths of staves indicated thereon; Fig. 9, a vertical longitudinalsection through the center of the table, showing a multiple-stave blanksevered in the center, the crozes formed and the forward stave extendingbeyond the outer end of the hinged section of the table, and thecutting-off and crozing tools, the table being hid in its raisedposition and on an enlarged scale; and Fig. 10, a perspective, on anenlarged scale, showing the stock-feed mechanism.

Reference being had to the drawings and the letters thereon, A indicatesthe frame of the machine, and B the top of the table, which is securedto the frame by hinges a Ct, only one of which is shown in Fig. 1, andis vertically movable to draw the strip down while it is being operatedupon by the cutting-off tool (J, having a line of cut transverse to theline of feed and the crozing-tools D D, the latter of which is providedwith cutters b c, which are arranged so that 0 makes an incisionsevering the grain of the wood in advance of the cutter 1), which shapesthe croze. The cutters are secured to the disks which support them bypieces of metal 01 and bolts 2, on whose heads are slight projections fto prevent their turning. The table is depressed by means of afoot-lever E, a rod F, and a lever G, the lever E being secured to theframe A by a hinge g, and the lever G is supported on a fulcrum H on thetable, the outer end of the lever being connected toeccentrically-mounted clamping-disks I I, supported in a frame orbracket h by the lever engaging a transverse. bar i, which is connectedat its ends to both of the disks. The disks are separated, so that onewill engage the stave K, that has been severed from the strip L justback of the croze 70, while the other disk engages the strip just backof the croze l, and clamp the strip and the stave to the table while thestave is being severed from the strip and the crozes formed in both. Bythis construction the table and the clamps are moved synchronously bythe foot of the operator.

M indicates an adjustable stop to limit the downward motion of thetable, and N a spring to raise the table and restore it to its normalposition after each operation of the cutting off tool and thecrozing-tools.

O is a fixed guide secured to the top of the table, and P alaterally-yielding guide pivotally secured to the table at m and held inengagement with the strip L by a spring n.

Q is a roller one end of which is supported in the guide 0, and theopposite end is supported in a bracket 0 and is arranged above the tablea distance equal to the thickness of the stripL to prevent its tiltingat the rear end as it is being fed into the machine.

R indicates the lower roller of an automatic feed to move the stripalong on the table and is supported on a bracket p, secured to the top Bof the table, as shown in Fig. 3, so that it rises and falls with thetop to engage the strip, and S the upper roller, supported on a bracketq, secured to the frame A, and is driven by a belt 0", engaging a pulleys on the shaft of the roller. As the table-top rises the pulley R risesand presses the strip L against the roller S. Thelatter feeds the stripto the cutting-tools, and when the table-top is depressed to cut andcroze the staves the strip is released from the feed during the cuttingaction.

T indicates a lever-clamp to hold the strip while the end is being cutoff and the croze cut in the end of the first stave cut from the strip.

U indicates a section of the table-top B, pivotally connected to theunder side of the table at t in rear of its longitudinal center, asshown in Fig. 2, narrower than the stave, and is provided at its outerend with a stop u, which is engaged by the front end of the,

oncoming strip to ride over the section without striking said inner end.The degree or extent of the drop of the front of the section U islimited by a support w, secured to the lower side of the table.

The cutting-off tool 0, which is a circular saw, and the crozing-tools DD are supported upon the main driving-shaft V of the machine and aresecured by nuts y y in the usual way of securing such tools.

Having thus fully described my invention,

what I claim is- 1. A machine for making staves from amultiple-stave-length blank provided with a vertically-movable table,means for depressing the table, and means for returning the table; incombination with a feed mechanism, a cut ting-off tool having a line ofcut transverse to the line of feed, and crozing-tools on opposite sidesand adjacent to the cutting-off tool.
